' Be it known that'FFREnERrox H. OEHLKE, United States, residing at 'Lo-" rain,fm the county of Lbral Ohio, has invented anew and useful Gasspecification.

Specification of Letters w s Application filed January 1, 1906: Serial n and State ofv of which the following is a This invention relates more particularly to employed in waterheating apparatus. The principal object. is to provide novel and exceedingly simple mechanism wherein the flow of gas for .heatin purposes is automati'cally controlled by tl i be heated, said mechanism being made up of arts that are readily assembled and are not iable to become deranged, though-easily accessible should they become worn, injured, or

noperative from any source. An embodiment of the invention that is at trated in the accompanying drawings, whereresponding parts in drawi Figure 1 is a sectional view through the structure, showing the as-valve closed and the operating means t Fig. 2 is a similar view, but showing the operating means maintaining the valve inopened 3 position. Fig. 3 is a detail perspective view 3 of the actuating-stein. 'ke numerals of reference designate corall.'-the figures of the s. a The gas-controlling means comprises a suitable valve-casing 4, having an inlet and outlet 5 andprovided with a guide projection 6 on one side and a tubular cap'7 on the other,

- the tubular cap being removable and referwhich pro ection is and its other en ably threaded into the casing. A we 8 ex- -tends across'the' interior of the casing and has a suitable opening 9 therein, said opening being surrounded by a valve-seat 10. A valve 11, located within the casin is movable into and ou'of coaction with t e seat 10 and i's carried bya stem-12, onestem being located in the cap 7, the other end extending through the guide provided with a suitable packing-box 13. A'coiled s ring 14, having one end bearingdagainst the top of the cap 1 1, urges said valve to closed position.

The operating means for the valve is prefably constructed as follows: A casing is provided, comprising sections and 16, the former being threaded. into the latter and end of the projection 6,

earing against the valve thecasings in fixed re e flow of water to erefor inoperative.

Anactuating member in the form of a diaphragm 23 extends across the chamber ormed within the sectional casing, the margins of saiddiaphra being clamped between the sections. liisfldia hragm carries a central plug 24, having a an e 25, that rests against one side of said diaphragm, and having a holdin collar or nut 26 threaded upon its end and earing a 'ainst the opposite side. The plug is movab e into and out of the inlet-nipplef17 and is provided with a passage-way 27, that extends throu 'h the 'aphragm, said passage-way inclu 'ng a transverse inlet portion 28. This inlet portion is so arranged that when the dia hragm is in its lowermost position and the p ug is 1n the inlet-Iii ple said inlet portion 28 will be substantiall y'closed b the walls of the ,m"

ple, or, in other wor s, by portions of t e.

When the plug is out of walls of the casin the inlet-nipple, however, thepassage-wriy is en, and, as shown in Fig. 2, water will ow ough the inlet-nip le, through the passage-way, and through the outlet. An ac' tuating-stem 29 is slidably mounted in the projecting lportion 19 of the casin and car'- ries at its ower endfia yoke or for 30, that rests uporrthe collar or nut 26, leavin an 0 en space for the free fl w ofsthe fiuid t 6ugh the passage-way 2.7. -The stem 29 projects beyond the casing in line with the valve-stem 12, which valve-stem it is arranged to strike when the diaphragm is moved'up:

OFFICE:

wardly. A packing-box 31 servesto 'prevent leakage aroun a coiled spring 32, surroun said stem, bears against the yoke and normally. urges the stem downwardly and away from the valve-stem 12. When the stem 29 is in its lowermost closed, the said the stem 12.

It is believed thatthe operation of the tem 29 will be spaced from the actuating-stem, and

position and when the valve 11 is I mechanism can now be reaTdil e'x lained. As lo g as the water is shut in t e pipe connected to the outlet-ni ple 18 the press'ure on both sides of the 'aphragm 23 will be equalized. Therefore the spring 32 will move said diaphragm downwardly, will cause the plug 24 to enter. the inlet-nipple,

and consequently close the passage-way 27. The valve-stem 12 being thus freed, the spring 14 will act to move said valve to closed position, and the supply of gas will be shut off. If, however, the outlet for the water 1s 0 ened, the pressure u on the outlet side of tie diaphragm will ing the plug out of 't'einlet and'permittin' the flow of water through said inlet, throu the passage-way 27, and through the out et 18. The upward movement of the diaphragm of course causes a corres onding movement of the actuating-stern an a compression of the spring 32. The upper end of the actuating-stem will in turn strike the val '-stem'1 2, thus moving said stem and the valve carried by it upwardly against the tension of the spring 14. As a result the I gaswill flow through the casing. As soon as the flow of water is stopped the parts will reassume their normal positions,- as shown in it will be apparent from an irfspection of the drawings that the structure is very sim-' ,ple and yet entirely efiective.

The. parts, moreover, are so arranged and are of such a nature that they are not liable to become deranged; yet should they become injured or ino erative from any reason they are all accessi le, and any one or more can be readily removed and relplaced without the necessity of an entire y new apparatus. The spacing of the stems 12 and 2 9 is a desirable feature in order to allow for the pulsation of the water and prevent the accidental opening of the gas-valve through back pressure. The diaphragm can of course be constructed of any suitable flexible material not subject to deterioration from contact with the water.

From the foregoing it is thought that the construction, operation, and 'many advantages' of the herein-described invention will be apparent to those skilled in the art without further description, and it will be under st god that various changes in the size, shape,

' proportion, and minor, details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
